hyperledger-fabric“编写您的第一个应用程序" query.js步骤失败 [英] hyperledger-fabric "Writing your first Application" query.js step fails

问题描述

步骤"git clone ..."，"startFabric.sh"和"npm.install"完成，没有错误. 节点query.js"结果为:

Steps "git clone...", "startFabric.sh" and "npm.install" complete with no errors. "node query.js" results in:

    Set wallet path, and associate user  PeerAdmin  with application
    error: [Client.js]: Failed to load user "PeerAdmin" from local key value store. Error: TypeError: this is not a typed array.

   Caught Error [TypeError: this is not a typed array.]

注意:在git clone步骤之后，如文档中所述，fabric-samples/fabcar中没有"chaincode"，但是fabric-samples中有chaincode/fabcar.这似乎没有引起问题. 注意:建立第一个网络"中的所有步骤都没有问题.

Note: after the git clone step, there is no "chaincode" in fabric-samples/fabcar as stated in the docs, but there is a chaincode/fabcar in fabric-samples. This does not seem to cause a problem. Note: All steps in "Building Your First Network" complete with no problems.

推荐答案

Hyperledger Fabric 1.0已针对Node.js版本> = 6.9和< 7.x.如果遇到类似错误，建议更新Node.js的版本(或使用版本管理器，例如nvm)，然后重试.如果已经使用较旧版本的Node运行npm install，则应删除node_modules树并重新运行npm install，以确保安装了正确的依赖项.

Hyperledger Fabric 1.0 has been tested against Node.js version >= 6.9 and < 7.x. If you get a similar error, recommend updating the version of Node.js (or use a version manager such as nvm) and re-try. If you have already run npm install with an older version of Node, you should delete the node_modules tree and re-run npm install to be sure you are installing the correct dependencies.
